The highway noise barrier also referred to as the sonic barrier, is employed for sound insulation between the noise source and therefore the noise-affected zone. They are called panels which are placed between them. These products, also termed as the noise barriers, they generally prevent the spread of traffic noise along lines like roads, bridges. This is why there is urgency and need for sound barrier technology.
It is also wont to prevent the spread of noise around machines like generators, compressors and therefore the like. On the noise source side, a number of the sound that hits the screen is absorbed by the screen. This also improves the background level on the sources
• Noise barriers helps in preventing bad noise from spreading to the environment
• Noise is trapped between its sources and doesn't spread to the environment.
• The Noise barriers made from rubber are often recycled.
• Durable for several years and costs little or no.
• Since it is often covered with artificial grass, an aesthetically beautiful appearance is made.
These are the small benefits of noise barriers. So noise stop technology are a really important detail for our lives. The utilization of noise barriers is extremely common in altogether developed countries. Because noise is linked to sophistication. The simplest thing about noise barriers is that they will be used for several years at no cost.
Sound is often music for one person and noise for the opposite. It's written that there was torture with noise in history. Nowadays, people are being punished by the extreme noise caused by irregular and unhealthy urbanization. Consistent with the classification, noise between 30-65 dB (decibel) is disturbing in some cases.
However, the form and size of the condition are extremely diverse. Insomnia starts at 45-50 dB. Some reactions occur within the system Nervosa between 65-90 DB. Noise between 90-120 dB starts to wreck the hearing organs. The Severe hearing impairments and deafness (loss of hearing) may occur if sounds during this dB persist for an extended time.
The most obvious sort of sound pollution is traffic noise. General elements to extend the noise; if there is increase in the population density,
What are the noise control and measures to scale back noise?
Noise control is quite feasible on the three levels. These helps in the reduction of the noise generated, preventing the access of the noise to the exposed ones (isolation of the source) and protection of the exposed ones. The primary of the measures covers the measures to be taken within the buildings of commercial establishments and in residential areas.
The second is to form use of the noise reduction properties of (biological) plants. The third one is to guard the individual with ear noise plugs. Town planning, separation of housing-industry-transportation places are the foremost important contemporary solution against noise.
One of the simplest measures to be taken is noise barriers. Because of the noise barriers, city life is often maintained more peacefully and vigorously.
Highway noise barriers
The elements which will be applied as highway noise prevention/reduction techniques are;
• Afforestation and the greening, using noise barriers
• Exhaust noise control, speed control of vehicles
• Giving priority to the noise-free conveyance
• Road construction material and road quality to scale back noise
• Acoustic standardization of building materials to make sure sound insulation in buildings
• Preventing unnecessary horns of automobiles
• Awareness raising of the general public and drivers
In the developed countries; natural and / or artificial noise barriers are further utilized in order to scale back the noise which mainly affects all the residential areas negatively or on highways with heavy traffic. The Curtains that are formed with natural plant species are more durable and economical than those made with artificial materials. Additionally, the plant species often feed on ecological and the biological wealth.
It is hence, reported that the noise of highways passing through city centres in the large cities of over 45 decibels, that forces human health, and affects the psychological state of these living within the surrounding settlements. Forty-five decibels should be avoided from the noise because the size of the noise increases the destruction of psychological state. Noisy environments cause tension and fatigue.
